[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] It should be noted that the terms "first" and "second" in this application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0029] The busbar installation process is specifically to first place the cell assembly on the busbar installation station, install the two end plates at the opposite ends of the cell assembly, and then install the busbar on the top of the cell assembly, sort out the busbar wire harness to make the busbar wire outlet. Then, the cell assembly is extruded and steel stripped to obtain a cell module. This embodiment provides installation assistance for the process of installing the busbar on the top of the cell assembly.

[0030] See also Figure 1 , Figure 1 It is a structural diagram of an embodiment of the installation auxiliary system of the present application.

[0031] The installation assistance system 100 of this embodiment includes: two identification units 120, a collection unit 130, a processing unit 110, and an interaction unit 140. The installation assistance system 100 is used to assist the busbar to be installed on the battery cell assembly.

[0032] The two identification units 120 are respectively arranged on opposite sides of the installation station of the busbar; wherein the identification data of the two identification units 120 are different. The identification data on the two identification units 120 can be distinguished from each other, and the specific types of identification data may include but are not limited to various visual patterns, frequency waves or audio, etc.

[0033] The collection unit 130 is used to collect the bus identification of the installed bus and the identification data of the identification unit on the same side as the actual outgoing line direction of the bus, and pre-reserve the collected data. In a specific application scenario, an identification device can be set on the collection unit 130 to identify the location of the actual outgoing line of the bus, and then collect the identification data of the identification unit 120 on the same side accordingly. In a specific application scenario, the collection unit 130 is a movable collection unit 130, and the operator can move the collection unit 130 to the identification unit 120 on the same side based on the actual outgoing line direction of the bus to collect identification data. The specific collection method is not limited here. The bus identification is the material number of the bus, which contains relevant information such as the model and the standard installation direction of the bus.

[0034] The specific type of the acquisition unit 130 can be determined based on the type of identification data to collect the identification data in a targeted manner. For example, when the identification data is a certain visual pattern, the acquisition unit 130 can be a pattern scanner. When the identification data is a certain frequency wave, the acquisition unit 130 can be a frequency receiver; when the identification data is a certain audio, the acquisition unit 130 can be a radio or a voice recognizer.

[0035] The processing unit 110 is connected to the acquisition unit 130, and is used to receive the bus identification and identification data transmitted by the acquisition unit 130, and judge whether the actual outgoing direction of the bus is correct based on the bus identification and identification data, and obtain a judgment result. The actual outgoing direction of the bus is compared with the standard installation direction in the bus identification to obtain a judgment result to determine whether the actual outgoing direction of the bus is correct.

[0036] Since the identification data on the two identification units 120 respectively arranged on the opposite sides of the busbar installation station are different, the processing unit 110 can know the actual outgoing direction of the installed busbar by identifying the identification data collected by the collection unit 130. The processing unit 110 further determines whether the actual outgoing direction of the installed busbar is correct and obtains a determination result.

[0037] If the bus identification matches the actual outgoing line direction, it means that the installation direction of this bus installation is correct. If the bus identification does not match the actual outgoing line direction, it means that the installation direction of this bus installation is wrong. Among them, the bus identification can be a string of characters, and the data at a specified position in the characters is used to express the standard outgoing line direction. For example: bus identification: xxxxx1xx and xxxxx0xx, wherein the third to last digit of the bus identification is used to express the standard outgoing line direction, 1 can be the left side, and 0 can be the right side. If the third to last digit of the bus identification is 1, and the actual outgoing line direction is the left side, then the bus identification matches the actual outgoing line direction, and if the third to last digit of the bus identification is 0, then the bus identification does not match the actual outgoing line direction. Among them, the processing unit 110 can specifically include a retrieval module and a comparison module, the retrieval module is used to retrieve relevant information of specified positions in various identifications, and the comparison module is used to compare and bind information between different identifications.

[0038] The interaction unit 140 is connected to the processing unit 110 to receive the determination result transmitted by the processing unit 110 and generate first interaction information based on the determination result to provide an installation reminder.

[0039] In a specific application scenario, the first interactive information may include a first reminder interactive action of an incorrect installation direction and a keep silent action of a correct installation direction, where the keep silent action means no reminder. If the judgment result is an installation error, an interactive reminder of an incorrect installation direction is output; if the judgment result is a correct installation, no interactive information may be output and silence may be maintained, thereby performing interactive reminders for different judgment results through the above distinction.

[0040] In a specific application scenario, the first interactive information may include a first interactive action to remind that the installation direction is wrong and a second interactive action to remind that the installation direction is correct. If the judgment result is that the installation is wrong, the first interactive action to remind that the installation direction is wrong is output; if the judgment result is that the installation is correct, the second interactive action to remind that the installation direction is correct is output. The first interactive action to remind is different from the second interactive action to remind, so that different judgment results are reminded through the above distinction.

[0041] Among them, the first interactive information can be output as a reminder in a variety of interactive ways, including but not limited to one or more of visual interaction, voice interaction, vibration interaction, etc. For example: the interactive reminder of the wrong installation direction can be a voice broadcast of "wrong installation direction", and the interactive reminder of the correct installation direction can be a voice broadcast of "correct installation direction". Or the interactive reminder of the wrong installation direction can be a text display of "wrong installation direction", and the interactive reminder of the correct installation direction can be a text display of "correct installation direction". Or the interactive reminder of the wrong installation direction can be a vibration reminder, and the interactive reminder of the correct installation direction can be silent, that is, no interactive reminder is made.

[0042] Through the above structure, the installation auxiliary system of this embodiment sets two identification units with different identification data on the opposite sides of the bus installation station, and after the bus is installed, based on the actual outgoing line direction of the installed bus, the identification data of the identification unit on the same side and the bus identification are collected by the collection unit and transmitted to the processing unit, so that the processing unit determines the actual outgoing line direction of the installed bus by identifying the identification data, and then judges whether the actual outgoing line direction of the bus is correct based on the bus identification and the identification data to obtain a judgment result; finally, the interaction unit generates the first interaction information based on the judgment result, and can determine whether the actual outgoing line direction of the installed bus is correct based on the matching judgment between the identification data of the identification unit on the same side as the actual outgoing line direction and the bus identification, and generates corresponding interaction information for reminder, thereby reducing the occurrence of the actual outgoing line direction of the bus being wrong during the installation process, and improving the reliability and production efficiency of the bus installation.

[0043] In some embodiments, the collection unit 130 is also used to collect the end plate identification of the battery cell assembly; the processing unit 110 is also used to receive the bus identification and the end plate identification transmitted by the collection unit 130, and output the comparison information after comparing the bus identification and the end plate identification; the interaction unit 140 is used to receive the comparison information and generate the second interaction information based on the comparison information. The comparison between the bus identification and the end plate identification is used to determine whether the bus model is installed correctly.

[0044] In some embodiments, the end plate identification is the material number of the end plate, including relevant information such as installation sequence, standard installation direction, installation model, etc. The busbar and end plate models installed on a battery cell assembly need to correspond to each other, so by comparing the busbar identification with the end plate identification, it is possible to determine whether the busbar model is correct with the help of the end plate identification.

[0045] In a specific application scenario, the second interactive information includes a third reminder interactive action for an incorrect installation model and a keep silent action for a correct installation model, where the keep silent action means no reminder. If the comparison information is an installation error, a reminder for an incorrect installation model is output; if the comparison information is a correct installation, no interactive information is output and silence is maintained, thereby performing interactive reminders for different comparison information through the above distinction.

[0046] In a specific application scenario, the second interactive information may include a third interactive action of reminding that the installation model is wrong and a fourth interactive action of reminding that the installation model is correct. If the comparison information is an installation error, the third interactive action of reminding that the installation model is wrong is output; if the comparison information is a correct installation, the fourth interactive action of reminding that the installation model is correct is output. The third interactive action of reminding is different from the fourth interactive action of reminding, so that different reminders of comparison information are given through the above distinction.

[0047] The second interaction information may be outputted in a variety of interactive ways, including but not limited to one or more of visual interaction, voice interaction, vibration interaction, etc. The specific means may be the same as the above embodiment, and will not be described in detail.

[0048] In summary, after the end plate and the bus are installed on the battery cell assembly, the installation assistance system 100 of this embodiment can also collect the end plate identification of the end plate on the battery cell assembly through the collection unit 130, and compare the bus identification and the end plate identification through the processing unit 110. If they do not match, it means that the installation model of the bus is incorrect, and the interactive unit 140 can be used to issue an error reminder of the installation model; if they match, it means that the installation model of the bus is correct, and the interactive unit 140 can be used to issue a correct reminder of the installation model or remain silent, so as to use the comparison of the bus identification and the end plate identification to determine whether the model of the installed bus is correct, and make corresponding interactive reminders, thereby reducing the occurrence of incorrect bus model installation during the installation process and improving the reliability and production efficiency of the bus installation.

[0049] Please read further Figure 2 , Figure 2 It is a structural schematic diagram of an implementation method of an identification unit.

[0050] In some embodiments, the identification unit 200 includes: an identification member 210 and a shieldable mechanism 220 .

[0051] The shieldable mechanism 220 includes a box body 221 and a cover 222, the cover 222 is movably connected to the box body 221, and the cover 222 is configured to be movable to open and close the box body 221, so that the identification unit 200 has two states, namely, an exposed state and a shielded state, and can switch between them.

[0052] Specifically, the cover plate 222 and the box body 221 can be hinged or separately arranged, and the identification member 210 is arranged in the box body 321, and the identification member 210 is used to provide identification data. Thus, by changing the relative position between the cover plate 222 and the box body 221, the box body 221 can be opened or closed to expose or shield the identification member 210 therein.

[0053] The identification member 210 may include, but is not limited to, a plate with a visual pattern formed thereon, a frequency wave transmitter, a buzzer, etc., which may be specifically determined based on the type of identification data. The material of the shieldable mechanism 220 may also be determined based on the type of identification data. For example, when the type of identification data is various visual patterns, the material of the shieldable mechanism 220 may be an opaque material; when the type of identification data is a frequency wave, the material of the shieldable mechanism 220 may be an electromagnetic shielding material; when the type of identification data is audio, the material of the shieldable mechanism 220 may be a soundproof material. When the identification member 210 is a frequency wave transmitter or a buzzer, the shieldable mechanism 220 may also be provided with a power supply, wires, switches, Bluetooth, and other basic equipment, which may be specifically provided based on actual needs.

[0054] See also Figure 3 , Figure 3 This is a schematic diagram of an exploded structure of another embodiment of the identification unit. This embodiment is applied to the scene where the type of identification data includes various visual patterns.

[0055] The identification unit 300 of this embodiment includes an identification member 310 and a shieldable mechanism 320 .

[0056] The shieldable mechanism 320 includes a box body 321 and a cover plate 322. The cover plate 322 is movably connected to the box body 321. Specifically, the cover plate 322 and the box body 321 can be hinged or separately arranged. The identification member 310 is arranged in the box body 321. The identification member 310 is used to provide identification data. Therefore, in different situations, the box body 321 can be opened and closed by changing the relative position between the cover plate 322 and the box body 321 to achieve shielding or exposure of the identification member 310 therein.

[0057] The above structure, by movably connecting the cover plate 322 with the box body 321, and the cover plate 322 is configured to be movable to open and close the box body 321 to expose or shield the identification member 310 therein, so that when collecting identification data, the shieldable mechanism 320 of the identification unit 300 on the same side can be opened based on the actual outgoing direction of the bus to expose the identification member 310 therein, so as to facilitate the collection of corresponding identification data. The shieldable mechanism 320 of the identification unit 300 on the other side continues to shield the corresponding identification member 310, so that the identification data cannot be collected, thereby reducing the occurrence of erroneous collection, that is, through the movable setting of the shieldable mechanism 320 to perform foolproof processing of the collection operation, improve the accuracy of identification data collection, and further improve the accuracy of bus auxiliary installation.

[0058] Please read further Figure 4 , Figure 4 It is a schematic diagram of the area division of a cover plate implementation method.

[0059] In some embodiments, the cover plate 322 includes a first portion 341 and a second portion 342 , and a junction 343 between the first portion 341 and the second portion 342 is rotatably connected to the box body 321 .

[0060] The first part 341 is used to place part of the bus. When the first part 341 is subjected to a force toward the inside of the box body 321, the second part 342 rotates toward the outside of the box body 321, so that the cover 322 rotates to an open state. When the force applied to the first part 341 is removed, the second part 342 rotates toward the inside of the box body 321, so that the cover 322 rotates to a closed state.

[0061] The cover plate 322 reveals the identification member 310 when it is in an open state, and shields the identification member 310 when it is in a closed state.

[0062] The bus includes a bus body, a wiring harness and a connector connected in sequence, and the outgoing wires of the bus body are gathered into a wiring harness and connected to the connector. In this embodiment, the part of the bus placed on the first part 341 is a connector. Among them, the connector is a structure that the bus itself has, and the connector is connected to the wiring harness of the bus, so that when determining the collected identification unit 300 based on the actual outgoing wire direction of the installed bus, the connector can be directly placed on the first part 341 in the identification unit 300 set on the same side, which is convenient for collecting the identification data on the same side.

[0063] Specifically, the connector is placed on the first part 341 of the cover 322 of the identification unit 300 to apply a force to the first part 341 toward the inside of the box body 321, and the second part 342 is rotated toward the outside of the box body 321, so that the cover 322 is rotated to an open state, so that the identification unit 300 on the same side as the actual outlet direction of the bus is in a naked state, so as to collect its identification data, thereby realizing the collection of the identification data of the identification unit 300 on the same side as the actual outlet direction of the bus.

[0064] The above-mentioned setting cleverly combines the existing connector and the identification unit 300 to jointly realize the collection of identification data of the identification unit 300 set on the same side as the actual outgoing direction of the bus, thereby improving the efficiency and accuracy of checking the actual outgoing direction of the bus. The operator only needs to place the connector connected to the outgoing line of the bus on the first part 341 of the identification unit 300 set on the same side based on the actual outgoing direction of the bus. At this time, the identification data of the identification unit 300 on the same side as the actual outgoing direction of the bus is exposed, while the identification data of the identification unit 300 on the different side from the actual outgoing direction of the bus continues to be shielded, which is convenient for accurate collection of identification data, simple logic, and convenient operation. The identification data on the other side is shielded to prevent the identification data on the other side from being mistakenly collected during collection. The above-mentioned setting can simultaneously achieve manual anti-foolproofing processing and equipment anti-foolproofing processing.

[0065] In some embodiments, please refer to Figure 3 and Figure 4 The roller 330 is disposed at the junction 343 between the first part 341 and the second part 342. Specifically, a through hole 323 is formed at the junction 343 between the first part 341 and the second part 342. The first part 341 and the second part 342 have the same size, that is, the junction 343 is located in the middle of the cover plate 322.

[0066] One end of the roller 330 is rotatably connected to an inner side of the box body 321, and the other end of the roller 330 passes through the through hole 323 until it is rotatably connected to the other opposite inner side of the box body 321; the roller 330 is a roller structure, which is a rolling cylindrical component.

[0067] Specifically, the roller 330 and the inner side of the box body 321 can be rotatably connected by a screw 331. The roller 330 and the inner side of the box body 321 can also be rotatably connected by an elastic structure.

[0068] The roller 330 and the cover plate 322 are fitted and fixed to each other, so that the cover plate 322 can drive the roller 330 to rotate together.

[0069] Since the roller 330 passes through the through hole 323 set in the middle of the cover plate 322, it is fixed to the cover plate 322. Therefore, when the cover plate 322 is not subjected to force, the gravity of the two opposite ends of the cover plate 322 is balanced, so that the cover plate 322 is arranged parallel to the horizontal direction. When the first part 341 of the cover plate 322 is subjected to force, the cover plate 322 will drive the roller 330 to rotate, thereby tilting, and the second part 342 rotates to tilt, thereby exposing the identification member 310 therein.

[0070] Please read further Figure 5-6 , Figure 5 It is a schematic diagram of an implementation method when the identification unit is in a shielding state. Figure 6 It is a schematic diagram of an implementation method when the identification unit is in an exposed state.

[0071] Please read first Figure 5 When the cover plate 322 is not affected by external force, the cover plate 322 is parallel to the bottom of the box body 321, that is, it covers the opening of the box body 321, thereby shielding the identification plate 312 therein.

[0072] Please refer to Figure 6 When the first portion 341 of the cover plate 322 receives a force from the connector 40 toward the box body 321, the first portion 341 moves downward under the force, and the second portion 342 tilts up with the help of the rotation of the roller 330, thereby exposing the identification plate 312 therein.

[0073] In some embodiments, please refer to Figure 3 , Figure 4 The identification member 310 includes an identification plate 312 on which identification data 311 is formed; the identification plate 312 is fixed to the second part 342 and is vertically arranged; when the first part 341 is subjected to a force toward the inside of the box body 321, the second part 342 rotates toward the outside of the box body 321, and the second part 342 drives the identification plate 312 to rotate and reveal the identification data 311 of the identification plate 312.

[0074] Among them, the depth of the identification plate 312 can be slightly smaller than the distance between the cover plate 322 and the bottom of the box body 321. For example, the depth of the identification plate 312 can be 92%-99% of the distance between the cover plate 322 and the bottom of the box body 321, including but not limited to: 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99%, etc.

[0075] Since the identification plate 312 is arranged on the second part 342, the overall dead weight of the second part 342 may be greater than that of the first part 341. The above structure occupies the bottom space of the second part 342 by setting the identification plate 312 fixed and vertically arranged with the second part 342. Therefore, when the first part 341 of the cover 322 does not bear the connector 40, the identification plate 312 is used to prevent the second part 342 from moving downward and causing the first part 341 of the cover 322 to tilt up. This allows the identification unit 300 to maintain a shielding state for a long time when it does not bear the connector 40, thereby reducing the occurrence of accidental exposure.

[0076] In some embodiments, the identification data 311 on the identification plate 312 includes, but is not limited to, one or more of an identification pattern, an identification word, an identification number, an identification color, an identification shape, or an identification letter. The identification pattern includes, but is not limited to, one or more of a QR code, a barcode, a pattern, a shape pattern, and a shadow pattern.

[0077] In a specific application scenario, the identification data on the identification unit 300 set on the left side of the bus installation station can be the word "left", and the identification data on the identification unit 300 set on the right side of the bus installation station can be the word "right". In a specific application scenario, the identification data on the identification unit 300 set on the left side of the bus installation station can be an odd number, and the identification data on the identification unit 300 set on the right side of the bus installation station can be an even number. The above description is only an example of the identification data 311 and is not limited.

[0078] In a specific application scenario, if it is necessary to install corresponding buses for multiple battery cell assemblies respectively, multiple identification data can also be set on the two identification units 300 based on the installation order of the battery cell assemblies. For example: If a battery pack has 4 battery cell assemblies and 4 buses need to be installed accordingly, based on the installation order of the battery cell assemblies and the standard outlet direction of each bus installation, serial numbers 1 and 3 can be set on the identification unit 300 on the left, and serial numbers 2 and 4 can be set on the identification unit 300 on the right. That is, it indicates that the standard outlet directions of the 4 buses are left, right, left, and right in the order of installation, which is convenient for the processing unit 110 to judge. When the battery pack has other numbers of battery cell assemblies and the corresponding number of buses need to be installed accordingly, the number of identifications and serial numbers on the identification unit 300 can also be set similarly based on the above method, which will not be repeated.

[0079] The various types of the identification data 311 can enable the identification unit 300 to have a variety of applicable scenarios, thereby improving the adaptability of the identification unit 300 to different collection methods.

[0080] In some embodiments, please refer to Figure 1 , the interaction unit 140 includes an audio interaction unit 141 and a display unit 142; the audio interaction unit 141 and the display unit 142 are both connected to the processing unit 110 to receive the judgment result or comparison information transmitted by the processing unit 110, so as to generate the first interaction information or the second interaction information based on the judgment result. Based on the different judgment results, the interaction mode of the audio interaction unit 141 may also be different, for example, the interaction content of the voice audio is different; or the correct judgment result audio may output brisk audio music, and the wrong judgment result audio may output tense audio music, which is not specifically limited here. The display unit 142 may also display different content corresponding to different judgment results, for example, under the correct judgment result or comparison information, the display unit 142 may display the word "correct", and under the wrong judgment result or comparison information, the display unit 142 may display the word "wrong"; and so on, which is not specifically limited here.

[0081] In a specific application scenario, the display unit 142 can also display the installation sequence of the battery cell components and the installation sequence of the busbars for the operator to view and identify.

[0082] The above structure can interact simultaneously through the audio interaction unit 141 and the display unit 142 to improve the interaction efficiency, thereby informing the installer of the installation status from multiple angles to facilitate the next installation process.

[0083] In a specific embodiment, the battery may include four cell assemblies, cell assembly 1, cell assembly 2, cell assembly 3 and cell assembly 4, and the corresponding buses are bus 1, bus 2, bus 3 and bus 4 respectively. Assuming that the models of the above four buses are different, the identification data in the left identification unit 120 of the bus installation station are 1 and 3, and the identification data in the right identification unit 120 of the bus installation station are 2 and 4.

[0084] Initialize the status of the installation auxiliary system and set corresponding parameters according to installation requirements.

[0085] When installing the battery cell assembly 1, if the operator installs bus 2, bus 3 or bus 4, the collection unit 130 collects the bus identification and the end plate identification, and compares them through the processing unit 110 to obtain comparison information of incorrect installation model. The interactive unit 140 then generates second interactive information of incorrect installation model to remind the installer to replace the bus. After replacement, the collection and comparison are performed again until the installation is correct. The interactive unit 140 then generates second interactive information of the correct installation model, thereby ensuring accurate installation of the bus models of the four battery cell assemblies.

[0086] Furthermore, if the bus installation model is correct and its actual outlet direction is on the right, the connector 40 is placed in the right identification unit 120. At this time, the left identification unit 120 is in a shielded state and the right identification unit 120 is in an exposed state. When the processing unit 110 detects, the designated parameter of the bus identification is an odd number, while the identification data is an even number, which does not match. The interactive unit 140 generates the first interactive information of the wrong installation direction to remind the installer to adjust the bus direction until the installation is correct. The interactive unit 140 generates the first interactive information of the correct installation direction to ensure that the four bus wiring directions are correct.

[0087] And when the bus and battery cell assembly are correct, the identification data on the left are set to 1 and 3, and the identification data on the right are set to 2 and 4, and it can also detect whether the orientation of the battery cell assembly is correct, thereby further improving the accuracy and reliability of the battery cell assembly installation.

[0088] This embodiment determines whether the installation model of the bus is accurate by collecting and comparing the bus identification and the end plate identification, and then determines whether the outgoing direction of the bus is accurate by collecting the identification data of the identification unit and comparing the bus identification and the identification number, so as to improve the installation accuracy of the bus from many aspects. In addition, this embodiment also uses the shieldable mechanism built-in identification parts that are movably connected between the cover plate and the box body to achieve the mutual switching of the exposed state and the shielded state of the identification unit, so as to expose the identification parts of the identification unit on the same side based on the actual outgoing direction, prevent the occurrence of erroneous collection of identification data, and improve the accuracy of identification data collection.

[0089] See also Figure 7 , Figure 7 It is a structural schematic diagram of an embodiment of the installation equipment of the present application.

[0090] The installation device 700 of this embodiment includes: a workbench 710, a mold carrier plate 720 and an installation auxiliary system (not shown).

[0091] The mold carrier 720 is fixedly arranged on the workbench 710 , and a busbar installation station 730 is formed on the mold carrier 720 ; the cell assembly 740 is installed with the end plate 760 and the busbar 750 at the busbar installation station 730 . The installation auxiliary system is arranged on the workbench 710 .

[0092] Specifically, the installation auxiliary system includes: two identification units 770, a collection unit, a processing unit and an interaction unit, the two identification units 770 are respectively arranged on opposite sides of the bus installation station 730; wherein, the identification data between the two identification units 770 are different, the collection unit is used to collect the identification data of the identification unit on the same side as the actual line-out direction of the installed bus, the processing unit is connected to the collection unit, and is used to receive the identification data transmitted by the collection unit, and determine the actual line-out direction based on the identification data, and judge whether the actual line-out direction is correct to obtain a judgment result, and the interaction unit is connected to the processing unit to receive the judgment result transmitted by the processing unit, so as to give a reminder based on the judgment result.

[0093] The identification unit 770 is movably mounted on the workbench 710 and can be connected by gluing or screws, but the two identification units 770 need to be respectively arranged on opposite sides of the busbar installation station 730 .

[0094] The installation auxiliary system of this embodiment includes the installation auxiliary system of any of the above embodiments. Therefore, through the above structure, the installation equipment of this embodiment can determine whether the actual outgoing direction of the bus after installation is correct with the help of the installation auxiliary system, and generate corresponding interactive information for reminder, thereby reducing the occurrence of the actual outgoing direction of the bus being wrong during the installation process, and improving the reliability and production efficiency of the bus installation. The installation auxiliary system can also collect and compare the bus identification and the end plate identification to determine whether the installation model of the bus is accurate.

[0095] See also Figure 8 , Figure 8 The installation assistance method of this embodiment is applied to the installation assistance system of any of the above embodiments, or the installation device of any of the above embodiments.

[0096] Step S11: in response to the completion of the installation of the bus, the identification data of the bus identification and the identification unit on the same side as the actual outgoing direction of the bus are collected.

[0097] Two identification units with different identification data are installed on opposite sides of the bus installation station. After the bus installation is completed, the identification data of the identification unit on the same side is collected based on the actual outgoing direction of the bus and the bus identification is collected. If the actual outgoing direction of the bus is on the left, the identification data of the identification unit on the left side of the bus installation station is collected; if the actual outgoing direction of the bus is on the right, the identification data of the identification unit on the right side of the bus installation station is collected.

[0098] It is sufficient that the identification data on the two identification units can be distinguished from each other. The specific types of identification data may include but are not limited to various visual patterns, frequency waves or audio, etc.

[0099] The bus identification is the material number of the bus, which includes the model, standard installation direction of the bus, and other related information.

[0100] Step S12: judging whether the actual outgoing line direction of the bus is correct based on the bus identification and identification data, obtaining a judgment result, and generating first interactive information based on the judgment result.

[0101] If the actual outgoing direction of the bus after installation is the left side, based on the identification data collected on the identification unit on the left side, it is determined that the actual outgoing direction of the bus is the left side. If the actual outgoing direction of the bus after installation is the right side, based on the identification data collected on the identification unit on the right side, it is determined that the actual outgoing direction of the bus is the right side.

[0102] Match the identification data with the bus identification to determine whether the actual outgoing line direction represented by the identification data is the same as the standard outgoing line direction of the bus identification tape. If they are the same, the bus identification matches the actual outgoing line direction, indicating that the installation direction of this bus installation is correct, and the judgment result is that the bus installation direction is correct. If they are not the same, the bus identification does not match the actual outgoing line direction, indicating that the installation direction of this bus installation is wrong, and the judgment result is that the bus installation direction is wrong.

[0103] After the judgment result is obtained, the first interactive information is generated based on the judgment result. In a specific application scenario, the first interactive information may include a first reminder interactive action for incorrect installation direction and a keep silent action for correct installation direction, where the keep silent action means no reminder. If the judgment result is an installation error, a reminder for incorrect installation direction is output; if the judgment result is a correct installation, no interactive information may be output and silence may be maintained, thereby performing interactive reminders for different judgment results through the above distinction.

[0104] In a specific application scenario, the first interactive information may include a first interactive action to remind that the installation direction is wrong and a second interactive action to remind that the installation direction is correct. If the judgment result is that the installation is wrong, the first interactive action to remind that the installation direction is wrong is output; if the judgment result is that the installation is correct, the second interactive action to remind that the installation direction is correct is output. The first interactive action to remind is different from the second interactive action to remind, so that different judgment results are reminded through the above distinction.

[0105] The first interactive information may be output as a reminder in a variety of interactive ways, including but not limited to one or more of visual interaction, voice interaction, vibration interaction, etc. For example, the interactive information of the wrong installation direction may be a voice broadcast of "wrong installation direction", and the interactive information of the correct installation direction may be a voice broadcast of "correct installation direction". Or the interactive information of the wrong installation direction may be a text display of "wrong installation direction", and the interactive information of the correct installation direction may be a text display of "correct installation direction". Or the interactive information of the wrong installation direction may be a vibration reminder, and the interactive information of the correct installation direction may be silent, that is, no interactive reminder is performed.

[0106] Through the above method, the installation assistance method of this embodiment collects the bus identification and the identification data of the identification unit on the same side as the actual outlet direction of the bus in response to the completion of the bus installation; judges whether the actual outlet direction of the bus is correct based on the bus identification and the identification data, obtains the judgment result, and generates the first interactive information based on the judgment result, so as to determine whether the actual outlet direction of the bus after installation is correct, and make corresponding interactive reminders, thereby reducing the occurrence of the actual outlet direction of the bus being wrong during the installation process, and improving the reliability and production efficiency of the bus installation.

[0107] In some embodiments, the busbar includes a busbar body, a wiring harness, and a connector that are sequentially connected.

[0108] In response to the completion of the bus installation, the steps of collecting the bus identification and the identification data of the identification unit on the same side as the actual outgoing direction of the bus include: installing the bus body on the battery cell assembly and arranging the wiring harness; placing the connector connected to the wiring harness on the cover plate of the identification unit on the same side to expose the identification data of the identification unit; collecting the exposed identification data and the bus identification.

[0109] The connector is a structure that the bus itself has, and the connector is connected to the wiring harness of the bus. Therefore, when the identification unit to be collected is determined based on the actual outgoing line direction of the bus after installation, the connector is directly placed on the cover plate of the identification unit set on the same side to expose the identification data of the identification unit, which is convenient for the collection unit to collect the identification data on the same side.

[0110] The above method cleverly combines the existing connector and identification unit to realize the collection of identification data of the identification unit set on the same side as the actual outgoing direction of the bus, thereby improving the efficiency and accuracy of the processing unit in checking the actual outgoing direction of the bus.

[0111] In some embodiments, the installation auxiliary method also includes: the installation auxiliary method also includes: installing end plates at opposite ends of the battery cell assembly respectively; collecting end plate identifications of each end plate.

[0112] Compare the end plate identification with the bus identification; when the end plate identification matches the bus identification, output comparison information indicating that the bus installation model is correct; when the end plate identification does not match the bus identification, output comparison information indicating that the bus installation model is incorrect; generate second interactive information based on the comparison information.

[0113] The end plate identification is the material number of the end plate, which contains relevant information such as installation sequence, standard installation direction, and installation model.

[0114] In a specific application scenario, the second interactive information includes a third reminder interactive action for an incorrect installation model and a keep silent action for a correct installation model. Keep silent means no reminder. If the comparison information is an installation error, a reminder for an incorrect installation model is output. If the comparison information is a correct installation, no interactive information is output and silence is maintained, thereby performing interactive reminders for different comparison information through the above distinction.

[0115] In a specific application scenario, the second interactive information may include a third interactive action of reminding that the installation model is wrong and a fourth interactive action of reminding that the installation model is correct. If the comparison information is an installation error, the third interactive action of reminding that the installation model is wrong is output; if the comparison information is a correct installation, the fourth interactive action of reminding that the installation model is correct is output. The third interactive action of reminding is different from the fourth interactive action of reminding, so that different reminders of comparison information are given through the above distinction.

[0116] The second interaction information may be outputted in a variety of interactive ways, including but not limited to one or more of visual interaction, voice interaction, vibration interaction, etc. The specific means may be the same as the above embodiment, and will not be described in detail.

[0117] The above method determines whether the bus installation model is correct by comparing and matching the end plate identification with the bus identification, and determines whether the bus installation direction is correct by comparing and matching the bus identification with the identification data, so as to improve the installation accuracy of the bus from the dual perspectives of model and direction.

[0118] See also Fig. 9 , Fig. 9 The installation assistance method of this embodiment is applied to the installation assistance system of any of the above embodiments, or the installation device of any of the above embodiments.

[0119] Step S31: setting the installation sequence of the plurality of bus bars corresponding to the installation sequence of the plurality of battery cell assemblies in the battery pack.

[0120] In a specific application scenario, assuming that the installation order in the battery pack is the first battery cell assembly, the second battery cell assembly, and the third battery cell assembly, the installation order of the busbars corresponds to the first busbar, the second busbar, and the third busbar. That is, the first busbar needs to be installed on the first battery cell assembly; the second busbar needs to be installed on the second battery cell assembly; and the third busbar needs to be installed on the third battery cell assembly.

[0121] The settings in this step are for the target design phase before installation.

[0122] Step S32: Install two end plates at opposite ends of the current battery cell assembly, and fix the busbar on the top of the current battery cell assembly.

[0123] The installation of the battery cell assembly is carried out one by one. First determine the current battery cell assembly. Install the two end plates at the opposite ends of the current battery cell assembly, and fix the busbar on the top of the current battery cell assembly.

[0124] Step S33: Arrange the wiring harness of the bus and place the connector connected to the wiring harness of the bus on the cover plate of the identification unit on the same side to expose the identification data of the identification unit.

[0125] The exposed identification data corresponds to the actual outgoing direction of the busbar, so that the processing unit knows the actual outgoing direction of the busbar by identifying the identification data.

[0126] Step S34: collecting the end plate identification of the end plate and the bus identification of the bus.

[0127] The busbar identification and end plate identification are the material numbers that come with the product, and both contain relevant information such as installation sequence, installation direction, and installation model.

[0128] Step S35: Determine whether the end plate identification and the bus identification match, if they match, execute step S36, if not, execute step S37.

[0129] If they do not match, it means that the installation model of the busbar installed this time is incorrect, for example, the third busbar may be installed on the second battery cell assembly, and then step S37 is executed.

[0130] If they match, it means that the installation model of the bus is correct, and then step S36 is executed.

[0131] Step S36: Collecting exposed identification data.

[0132] When the installation model of the bus is correct, the installation direction of the bus is further determined by first collecting the exposed identification data to determine the actual outgoing direction of the bus. The outgoing direction of the bus is corresponding to its installation direction. If the outgoing direction is correct, the installation direction is correct. If the outgoing direction is wrong, the installation direction is wrong.

[0133] Step S37: Replace the busbar on the top of the current battery cell assembly.

[0134] When the installation model of the busbar is wrong, the busbar on the top of the current battery cell assembly is replaced, and step S33 is executed again to make a corresponding judgment again.

[0135] Step S38: Determine whether the identification data matches the bus identification. If so, execute step S39; if not, execute step S40.

[0136] Determine whether the identification data matches the bus identification. If they match, it means that the installation direction of the bus is correct, that is, at this time, the installation model and installation direction of the bus of the current battery cell assembly are correct, then execute step S39; if they do not match, it means that the installation direction of the bus is wrong, that is, at this time, the installation model and installation direction of the bus of the current battery cell assembly are correct, then execute step S40.

[0137] Step S39: The busbar of the current battery cell assembly is installed to obtain a battery cell module.

[0138] After the busbar of the current battery cell assembly is installed, a new current battery cell assembly can be obtained, and step S32 is executed again to continue installing the new current battery cell assembly until all battery cell assemblies in the battery pack are installed.

[0139] Step S40: adjusting the installation direction of the busbar on the top of the current battery cell assembly.

[0140] After adjusting the installation direction of the busbar on the top of the current battery cell assembly, step S33 is executed again. The order of step S33 and steps S34-S35 of this embodiment can be swapped, that is, the installation model is judged first, and then the exposed identification data is collected, so as to reduce the number of steps in the process of re-executing step S33 in this step and improve the installation efficiency.

[0141] Through the above steps, it is possible to determine whether the installation direction and installation model of the bus of each battery cell assembly are correct, and generate corresponding interactive information for reminders, thereby reducing the occurrence of bus installation errors during the installation process and improving the reliability and production efficiency of the bus installation.
